Description

Technical Field

[0001] This utility model relates to the field of gas station technology, specifically to a comprehensive utilization system for self-generated steam from a gas generator and a gas station. Background Technology

[0002] In the process of coal gas production, the coal gasifier is one of the important core equipment. The coal gasifier produces coal gas by heating solid fuels, such as coal, inside the furnace. In order to protect the furnace body and other components, a cooling water jacket is usually installed around the circumference of the furnace body to cool it down. The steam generated by the water in the cooling water jacket after cooling the furnace body is generally collected through a steam drum.

[0003] In related technologies, gas-water separation is generally carried out inside the steam drum. The collected water flows back into the cooling water jacket of the gasifier, while most of the steam is directly discharged to the outside after being stored in the steam drum, resulting in a waste of water and heat energy. Utility Model Content

[0004] The technical problem to be solved by this utility model is: how to save energy.

[0005] This utility model provides a comprehensive steam utilization system for a gasifier, comprising a gasifier, a steam drum, steam-using equipment, a condenser manifold, and a water collection tank. The cooling water jacket of the gasifier is connected to the steam drum and the water collection tank respectively. The steam drum, the steam-using equipment, and the condenser manifold are connected in sequence. An air inlet pipe is provided at the bottom of the gasifier, and a heating water jacket is provided on the outer circumference of the air inlet pipe. The heating water jacket is connected between the condenser manifold and the water collection tank.

[0006] Optionally, the gasifier self-generated steam comprehensive utilization system further includes a lifting water tank, which is connected to the cooling water jacket of the gasifier, and the height of the lifting water tank is higher than the height of the cooling water jacket of the gasifier. A lifting water pump is installed in the lifting water tank and is connected to the collection water tank.

[0007] Optionally, a level gauge is installed in the lifting water tank, and the level gauge is electrically connected to the lifting water pump.

[0008] Optionally, the gasifier self-generated steam comprehensive utilization system further includes a soft water tank, which is equipped with a softening treatment device. The softening treatment device is connected to the booster water tank, and the soft water tank is connected to the cooling water jacket of the gasifier.

[0009] Optionally, the gas generator self-generated steam comprehensive utilization system further includes a filtration device, which is connected between the condensate collection pipe and the heating water jacket.

[0010] Optionally, the gas generator self-generated steam comprehensive utilization system further includes a heat exchanger, which is connected between the filter device and the collection water tank.

[0012] Optionally, an overflow pipe is provided at the upper end of the water collection tank.

[0013] Optionally, a water injection pipe is provided at the upper end of the water collection tank.

[0014] Compared with the prior art, the gasifier self-generated steam comprehensive utilization system provided by this utility model has the following technical effects:

[0015] This utility model provides a comprehensive steam utilization system for a gasifier, applicable to gas stations. The high-temperature steam generated by the gasifier can be collected and temporarily stored via a steam drum. By installing a condensation collection pipe and connecting the steam drum, steam-using equipment, and the condensation collection pipe sequentially, the high-temperature steam can be applied to steam-using equipment such as intercoolers, primary electrostatic precipitators, secondary electrostatic precipitators, and air coolers within the gas station for insulation and purging operations during maintenance. This replaces the previous requirement of separately adding a medium for insulation or purging of steam-using equipment, saving costs. The high-temperature steam is then condensed and collected at a certain temperature via the condensation collection pipe. Hot water is used in the gasifier. A heating water jacket is installed around the outer circumference of the air inlet pipe at the bottom of the gasifier and connected to a condenser pipe. The hot water collected in the condenser pipe preheats the air in the air inlet pipe, allowing the air used for combustion heating in the gasifier to be preheated, thus improving the gasifier's operating efficiency. Furthermore, a collection tank collects the cold water formed after heat exchange in the heating water jacket, which is then used to replenish the gasifier's cooling water jacket. This creates a cycle of high-temperature steam generated by the gasifier, effectively utilizing energy and saving water and heat energy. This not only improves overall operating efficiency but also reduces costs.

[0016] In addition, this utility model also provides a gas station, including the above-mentioned gas generator self-generated steam comprehensive utilization system.

[0017] Compared with the prior art, the gas station provided by this utility model has roughly the same technical effect as the aforementioned gas generator self-generated steam comprehensive utilization system by setting up the gas generator self-generated steam comprehensive utilization system, and will not be described in detail here.

Therefore, it should not be construed as a limitation on the scope of protection of this utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] In the description of this specification, references to terms such as "embodiment," "one embodiment," and "one implementation" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or illustrative embodiment of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0027] To solve the above technical problems, such as Figure 1 and Figure 2 As shown, this utility model embodiment provides a comprehensive utilization system for self-generated steam from a gasifier, including a gasifier 1, a steam drum 2, a steam-using device 3, a condenser collecting pipe 4, and a water collection tank 6. The cooling water jacket of the gasifier 1 is connected to the steam drum 2 and the water collection tank 6 respectively. The steam drum 2, the steam-using device 3, and the condenser collecting pipe 4 are connected in sequence. An air inlet pipe 101 is provided at the bottom of the gasifier 1, and a heating water jacket 5 is provided on the outer circumference of the air inlet pipe 101. The heating water jacket 5 is connected between the condenser collecting pipe 4 and the water collection tank 6.

[0028] It should be noted that there are multiple steam-using devices, such as... Figure 1The diagram only illustrates three steam-using devices 3. Furthermore, gas stations typically also include intercoolers, primary electrostatic precipitators for heavy oil, secondary electrostatic precipitators for oil removal, and air coolers, which work together with the gasifier 1 to produce and purify the gas. These steam-using devices 3 require purging during regular maintenance. Previously, this was typically done by adding a purging pump connected to nitrogen or other media. Additionally, the steam-using devices 3 require a certain temperature to operate; for example, in cold environments like winter, additional heating and insulation are necessary. In other words, both insulation and purging previously required additional media and energy. This embodiment effectively utilizes the high-temperature steam produced by the gasifier 1, thus saving these media and energy resources. Meanwhile, it should be understood that in this embodiment, for example, the connection between the steam package 2 and the steam-using equipment 3, as well as the connection between various devices, is made through pipelines. Furthermore, for example, when performing insulation and purging operations on the steam-using equipment 3, separate valves and pipelines can be set up to regulate each steam-using equipment 3. Of course, when the steam-using equipment 3 does not require high-temperature steam for insulation or purging operations, it can also be directly connected to the condensate collection pipe 4 through the cooperation of valves and pipelines to obtain hot water through condensation. It is also understood that after the high-temperature steam is condensed into water through the condensate collection pipe 4, the resulting condensate also has a relatively high temperature, generally above 60°C, and can be used as preheating energy for the air required by the gasifier 1.

[0029] Specifically, the gas generator 1 is a two-stage gas generator, and two sets of cooling water jackets are arranged around the outer circumference of the furnace body. Each of the two sets of cooling water jackets is connected to a steam package 2, which improves the overall efficiency of gas production and steam utilization. Meanwhile, the air inlet pipe 101 at the bottom of the gasifier 1 is used to supplement the gas for combustion and heating in the gasifier 1, providing the required medium. A hot water jacket 5 is installed on the outer circumference of the air inlet pipe 101 to preheat the air entering the gasifier 1 through the air inlet pipe 101. The hot water jacket 101 heats the air through heat exchange on the pipe wall to improve the efficiency of the gasifier 1, which is especially effective in the cold winter environment in the north. At the same time, a condensate inlet 501 is provided at one end of the hot water jacket 5, and a condensate outlet 502 is provided at the other end. The condensate inlet 501 is connected to the outlet of the condensate collection pipe 4, and the condensate outlet 502 is connected to the collection water tank 6. The cold water formed after the hot water collected by the condensate collection pipe 4 is effectively utilized flows into the collection water tank 6, so that both water energy and heat energy are effectively utilized, saving energy and avoiding energy waste.

[0030] In this embodiment, the gasifier-generated steam comprehensive utilization system provided can be applied to a gas station. The high-temperature steam generated by the gasifier 1 can be collected and temporarily stored through the steam drum 2. By setting up a condensation collection pipe 4 and connecting the steam drum 2, steam-using equipment 3, and the condensation collection pipe 4 in sequence, the high-temperature steam can be applied to steam-using equipment 3, such as the intercooler, primary electrostatic precipitator, secondary electrostatic precipitator, and air cooler in the gas station, for equipment insulation and purging operations during maintenance. This replaces the previous requirement to separately add a medium for insulation or purging operations of the steam-using equipment 3, saving costs. After the high-temperature steam is processed, it is condensed and collected through the condensation collection pipe 4 to a temperature of a certain value. Hot water is used in the gasifier 1. A heating water jacket 5 is installed around the outer circumference of the air inlet pipe 101 at the bottom of the gasifier 1 and connected to a condenser pipe 4. The hot water collected in the condenser pipe 4 preheats the air in the air inlet pipe 101, allowing the air used for combustion heating in the gasifier 1 to be preheated, thus improving the operating efficiency of the gasifier 1. Furthermore, a collection tank 6 collects the cold water formed after heat exchange in the heating water jacket 5, which is then used to replenish the cooling water jacket of the gasifier 1. This creates a cycle of high-temperature steam generated by the gasifier 1, effectively utilizing energy and saving water and heat energy. This not only improves overall operating efficiency but also saves costs.

[0031] Optionally, such as Figure 1 As shown, the gasifier self-generated steam comprehensive utilization system also includes a lifting water tank 7, which is connected to the cooling water jacket of the gasifier 1, and the height of the lifting water tank 7 is higher than the height of the cooling water jacket of the gasifier 1. A lifting water pump is installed in the lifting water tank 7, and the lifting water pump is connected to the collection water tank 6.

[0032] Specifically, the gas generator 1 has a cylindrical structure, and the water inlet of the cooling water jacket on the outer circumference of the furnace body is located at its upper end. In order to facilitate the replenishment of water to the cooling water jacket, the water tank is higher than the cooling water jacket. In order to facilitate the collection of condensate, the collection water tank 6 is generally located on the ground. Furthermore, the cooling water jacket is replenished more conveniently by setting up the lifting water tank 7.

[0033] In this embodiment, by setting up a lifting water tank 7 and installing a lifting water pump inside it, the lifting water pump can draw the cold water collected in the collection water tank 6 into the lifting water tank 7, which is located at a higher position. At the same time, by setting the height of the lifting water tank 7 higher than the height of the cooling water jacket of the gasifier 1, it is easier to replenish the cooling water jacket, which facilitates operation and improves efficiency.

[0034] Optionally, such as Figure 1As shown, a level gauge is installed inside the lifting water tank 7, and the level gauge is electrically connected to the lifting water pump.

[0035] Specifically, the level gauge is an electronic level gauge, and it can be set to two positions, high and low. For example, if the water level is lower than a threshold, it means that there is a shortage of water in the lifting tank, so a signal is sent to the lifting water pump to make it work to draw water. If the water level is higher than the level gauge at the high position, that is, higher than a certain threshold, a signal is sent to the lifting water pump to stop working, so as to facilitate precise operation.

[0036] In this embodiment, by installing a level gauge in the lifting water tank 7 and electrically connecting it to the lifting water pump, the water level information of the lifting water tank 7 can be obtained through the level gauge. At the same time, it is convenient to control the operation of the lifting water pump, which facilitates automatic operation and further improves the operation efficiency.

[0037] Optionally, such as Figure 1 As shown, the gasifier self-generated steam comprehensive utilization system also includes a soft water tank 8, which is equipped with a softening treatment device. The softening treatment device is connected to the lifting water tank 7, and the soft water tank 8 is connected to the cooling water jacket of the gasifier 1.

[0038] Specifically, the softening device refers to a device for softening water to reduce hardness ions such as calcium and magnesium in the water. The softening device can be, for example, an ion exchange resin softening device, which uses exchangeable ions in the ion exchange resin to replace hardness ions such as calcium and magnesium in the water, thereby removing hardness ions and achieving the purpose of softening water. It can also be an electromagnetic softening device, which changes the physicochemical properties and crystallization state of hardness ions such as calcium and magnesium in the water by applying an electromagnetic field of a certain intensity and frequency, making them less likely to form scale, thereby achieving the effect of softening water, and thus protecting components such as the cooling water jacket of the gasifier 1 and improving their service life.

[0039] In this embodiment, a soft water tank 8 is connected between the lifting water tank 7 and the cooling water jacket of the gasifier 1, and a softening treatment device is installed in the soft water tank 8. The softening treatment device can soften the water in the lifting water tank 7 to remove high hardness ions such as calcium and magnesium, and then the water is added to the cooling water jacket of the gasifier 1. This can prevent the formation of difficult-to-maintain conditions such as scale in the cooling water jacket and improve the overall service life.

[0040] Optionally, such as Figure 1 As shown, the gas generator self-generated steam comprehensive utilization system also includes a filter device 9, which is connected between the condensate collection pipe 4 and the heating water jacket 5.

[0041] Specifically, the filter device 9 can be a physical filter component, such as a filter for asbestos or a filter membrane, which can filter out residues and other impurities in the condensate. Its specific structure is not specifically limited here.

[0042] In this embodiment, by connecting a filter device 9 between the condensate collection pipe 4 and the heating water jacket 5, the filter device 9 can filter out impurities such as residues in the condensate collected by the condensate collection pipe 4, such as residues brought in after the high-temperature steam passes through the intercooler, the first-stage electrostatic precipitator, the second-stage electrostatic precipitator and the air cooler and other steam-using equipment 3 for heat preservation and purging operations, thereby improving the water quality of the condensate and preventing it from affecting the subsequent heating water jacket 5 and the cooling water jacket of the gasifier 1, making the overall operation more stable and reliable.

[0043] Optionally, such as Figure 1 As shown, the gas generator self-generated steam comprehensive utilization system also includes a heat exchanger 10, which is connected between the filter device 9 and the collection water tank 6.

[0044] Specifically, the heat exchanger 10 can be a heating device such as a radiator, which can keep the environment warm. Of course, it is understood that a valve body can be added to the pipeline connected to the heat exchanger 10. In cold winter, for example, when the heat exchanger 10 needs to work, the valve body opens to supply water.

[0045] In this embodiment, a heat exchanger 10 is connected between the filter device 9 and the collection water tank 6, so that the hot water generated by the high-temperature steam through the condensation collection pipe 4 can be used for heat exchange, such as for environmental heating, and the thermal energy can be further utilized. At the same time, the cold water after heat exchange can also enter the collection water tank 6 to replenish the cooling water jacket of the gasifier 1, so as to further make full use of water energy and thermal energy.

[0046] Optionally, such as Figure 1 As shown, the gas generator self-generated steam comprehensive utilization system also includes a high-pressure pump 11, which is connected to the filter device 9.

[0047] Specifically, the high-pressure pump 11 can be, for example, the high-pressure pump 11 of a high-pressure water truck in a gas station, which can perform cleaning and other operations on the environment and equipment in the gas station.

[0048] In this embodiment, by setting up a high-pressure water truck 11 and connecting it to the filter device 9, the water collected by the condensate collection pipe 4 can be filtered and introduced into the high-pressure pump 11, so that the condensate can be further utilized. For example, it can be pressurized by the high-pressure pump 11 to clean the environment or equipment, thereby further utilizing water energy and preventing waste.

[0049] Optionally, such as Figure 1As shown, an overflow pipe 601 is provided at the upper end of the water collection tank 6.

[0050] Specifically, the overflow pipe 601 is equipped with an overflow valve to provide overflow protection when the gas or water in the collection tank 6 reaches a certain pressure. Of course, the overflow pipe 601 can be connected to other pipes to a designated discharge pipe.

[0051] In this embodiment, by providing an overflow pipe 601 at the upper end of the water collection tank 6, overflow protection can be provided for the water collection tank 6 and the connected pipes, making the overall operation safer and more reliable.

[0052] Optionally, such as Figure 1 As shown, a water injection pipe 602 is provided at the upper end of the water collection tank 6.

[0053] Specifically, the water injection pipe 602 can be connected to a water source to replenish the water collection tank 6. Of course, the water injection pipe 602 can also be connected to a control valve body and a pump body, and connected to a water source for automatic water replenishment.

[0054] In this embodiment, by setting a water injection pipe 602 at the upper end of the water collection tank 6, water can be added to the water collection tank through the water injection pipe 602. For example, when the amount of condensate collected by the condensation collection pipe 4 is insufficient to replenish the cooling water jacket of the gasifier 1, water can be added through the water injection pipe 602. The design is reasonable, making the whole system more stable and reliable.

[0055] In addition, another embodiment of this utility model provides a gas station, including the above-mentioned gas generator self-generated steam comprehensive utilization system.

[0056] For example, the gas station is equipped with multiple gas generators 1, and the multiple gas generators 1 can be connected through pipelines and valves to make more comprehensive use of the steam produced by the gas generators 1.

[0057] In this embodiment, the gas station provided in this embodiment has the same technical effect as the gas generator self-generated steam comprehensive utilization system described above, and will not be described again here.

[0058] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
